5/28 — Week 2 — Time and Motion (John Whitney)

[tarngerine]

• Started with going over homework with Karina, Ming (Ophelia), Nun

Discussed quotes from Vera Molnar article

Now I have to really think about what I am doing while drawing in order for Jeff to write a program to deal with what I can do as second nature. This thinking has made the making of the hand work much clearer.

Audio + Images

Synchrony, Mary Ellen Bute (Houston, TX):

We will take a mathematical formula and put it into terms of moving forms, music and color. They will tell a story to the eye and the ear. A legend can be built thus around arithmetical or logarithmic...
Dada (1936) - dancing shapes to music, 2d and 3d, cubes flying around, lines coming in like bohemian rapsody in fantasia.
Oskar Fischinger
Normal Mclaren - Pen Point Percussion

Brothers took WW2 decommisioned machines to make animations

In the future, artists may need to learn programming in order to practice their craft

John Whitney — famous for developing video
Also has a brother, James Whitney

1961 — Catalog, created on analog computers

Using math to drive image and sound, working with IBM/programmers, write software on computer screen, film camera pointed at a monitor, make frame by frame animation. A lot of film in 70s are computer made

Book recommendation for audio/visual expression


Everything is a wave form: light, sound. Tools to map from one wave form to another

Whitney wrote a book on the internetarchive

Polar coordinates with a lot of params

[tarngerine]

So much of his work is MATH

frequency
phase
amplitude

sin/cos

Use one sin to control another sin
Take one freq to modulate another freq
"freq modulation"

Math to drive movement and sound, not necessary to do sound for homework, but is a fun extra

Japanese artist: masahi kosato + student films


two sin waves with diff frequency > spiral form called "Leueeiufoawwaef"

Technical notes

ofGetElapsedTimef() outputs in seconds, multiply to increase speed
feed into sin as angle, always output as -1 and 1
ofMap() to map that -1 to 1 range to ofGetWidth()
6.28s to go 1 full cycle (2 * pi)
ofDrawCircle(x y r)

• frequency > vary speed using loop

see patterns in the lines

• phase > shift left/right

• amplitude >

lay things out in a circle, or move in circular pattern, use sin / cos

Homework

Reading

book: articulated lights

collection of artist statements, pick 1 to read

Recreation

John Whitney, something like a 5-10s loop
